However computer navigation has a substantial learning curve and the use of commercially available navigation systems increases surgical time. In addition the potential risks associated with the navigation TKA such as registration errors notching of the anterior femoral cortex oversizing of the femoral component and overresection must be taken into consideration. On the other hand conventional techniques are familiar and intuitive to most practicing surgeons and thus are easier to perform and are less prone to anterior notching and femoral component oversizing. However conventional techniques have greater risks of inaccurate and inconsistent component alignment than computer navigation. This paper describes a novel technique that combines computer navigation and conventional TKA. Introduction The use of computer navigation for primary total knee arthroplasty TKA provides the benefits of accurate bone resection low outlier frequencies and the restoration of overall mechanical alignment. However its use also involves the disadvantage of change in technique and workflow that have been associated with steep learning curve and increased surgical time. Furthermore several investigators have described the potential risks associated with the use of navigation which include registration errors notching of the anterior femoral cortex oversizing of the femoral component and overresection 1-4 . These risks mean that surgical plans provided by navigation software might require modification intra-operatively based on the surgeon s .
